What is the best way to set up in this scenario? Should I use the UV Cut or not on papers with high levels of OBA.
It's not so much about the paper - it's about your viewing conditions. You will get the best visual match if the effective instrument illumination is similar to that of your viewing conditions with regard to UV output. So UV cut (M2) is appropriate if your viewing conditions are UV poor (ie. Incandescent filtered by glass). If pure Incandescent, then M0 would be appropriate. If you are in natural light then something that more accurately simulates D50, such as M1 would be appropriate. If you are using a viewing booth, then it depends on the UV output of the lamps, which in the past was rather variable. As usual, you get better matches if you use the actual viewing illuminant spectrum to compute the XYZ values from the reflectance rather than the default ICC/Graphic Arts assumption of D50.
